UNITED STATES ROBERT WILSON, OF GREENUP, KENTUCKY.

PATENT OFFIC AIR SEPARATOR AND FEEDER FOR BOLTS, 80C.

SPECIFICATION forming part of Letters Patent No. 271,389, dated January 30, 1881- Application filed September 16, L882.

To all whom it may concern:

Be it known that I, ROBERT WILSON, of

.Greenup, in the county of Greenup and State of Kentucky, have invented certain new and useful Improvements in Air Separators and Feeders for Bolts, &c., of which the following is a full, clear, and exact description.

The object of my invention is to provide certain new and useful improvements in air IO separators and feeders for bolts, &c., whereby the flour can be removed from the chop and the heat caused by the grinding will be removed from the bolter.

The invention consists in the combination 1 and arrangement of parts substantially as hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure l is a perspective view of my improved attachment for bolters. Fig. 2 is a longitudinal sectional elevation of the same. A tube, A, is secured vertically on the top 2 of the bolter B, and is provided at its lower end with an inverted-tunnel-shaped cap, 0, which has its lower wider edge secured on the top of the bolter, over the feed-opening of the same. On the top of the tube the fan-casing D is secured, which is provided with an outlet, E.

The fan-wings F are attached to a tubular shaft, G, provided on the top of the fan-casing with a belt-pulley, H. The fan rotates in the horizontal plane.

A shaft, 1, connecting with the tubular shaft G by arms I, and extending down through the tube A, is provided'with a series of inclined radial scattering-blades, J, and has its 40 lower end stepped in a cross-piece, K, at the lower end of the tube.

(No model.)

A tube, L, projects from the top of the easing D through the tubular shaft G.

The tube A is provided at its lower end with a series of ports, M, which can be closed by slides N or equivalent devices, through which ports M the air enters.

The shaft 1 can extend down to the top of the bolting-reel, but must never be connected with the same, but supported by a step.

The operation is as follows: The air enters through the ports M, which are opened more or less by means of the slides N, and the current of air passes upward through the tube A, the fan-casing D, and its outlet E. The meal passes down through the tube L and drops upon the scattering-wings J, by which it.is scattered in the tube A: The flour is carried upward and out through the outlet E by the current of airand the meal dropsinto the bolter. The fan also draws all the hot air produced by the grinding-stones from the bolter, so that the air iu the same will always be fresh and 0001.

Having thus fully described my invention,

I claim as new and desire to secure by Letters 6 Patent- 1. The combination of the tube A, the fancasing D, the tubular shaft G, the fan-wings F, and the pulley H, substantially as herein shown and described, and for the purpose set forth.

2. The combination of the tube A, having ports M in its lower end, the fan-casing D, the tubular shaft G, the fan-wings F, the tube L, the shaft I, having scattering-blades J, and 7 the slides N for closing the ports M, substantially asand for the purpose set forth.

ROBERT WILSON.
